Brief Summary

There are so many contradictions over central lymph node dissection in unilateral cN0(Clinically N0) differentiated thyroid carcinoma.In order to provides a new theoretical basis for the operation of central lymph node in cN0(Clinically N0) differentiated thyroid cancer,researchers are going to complete this study to evaluate the significance of contralateral central lymph node dissection in unilateral cN0(Clinically N0) differentiated thyroid carcinoma.At the same time,it may play a certain impact on the revision of surgical guidelines for differentiated thyroid cancer.

Outcome Measures

Primary Outcomes (3)

  • Tumor diameter

    Tumor diameter will be measured by postoperative pathological examination.

    12 months

  • Number of lymph nodes dissected in every side of central lymph node

    Count the number of lymph nodes dissected during operation in every side of central lymph nodes of every Participants.

    12 months

  • Number of metastatic lymph nodes diagnosed by Postoperative pathology

    Count the number of metastatic lymph nodes diagnosed by Postoperative pathology in every side of central lymph nodes of every Participants.

    12 months

Secondary Outcomes (1)

  • Rate of lymph nodes metastasis

    12 months

Study Arms (2)

Tumor diameter<=2cm study group
